Quantitative analysis of DNA‐GATA1 binding alterations linked to hematopoietic disorders

The FEBS Journal, EarlyView.
Native holdup allows the quantitative determination of affinities between full‐length transcription factors and DNA. Mutations in either the protein or the DNA can modulate binding strength, which can be precisely quantified using this approach. Applied to GATA1, it revealed mutations that alter DNA binding.

ADP-ribose polymers localized on Ctcf–Parp1–Dnmt1 complex prevent methylation of Ctcf target sites [PDF]

Biochemical Journal, 2011
PARylation [poly(ADP-ribosyl)ation] is involved in the maintenance of genomic methylation patterns through its control of Dnmt1 [DNA (cytosine-5)-methyltransferase 1] activity. Our previous findings indicated that Ctcf (CCCTC-binding factor) may be an important player in key events whereby PARylation controls the unmethylated status of some CpG-rich ...

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

The FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This

Exploring the changing landscape of cell-to-cell variation after CTCF knockdown via single cell RNA-seq

BMC Genomics, 2019
Background CCCTC-Binding Factor (CTCF), also known as 11-zinc finger protein, participates in many cellular processes, including insulator activity, transcriptional regulation and organization of chromatin architecture.

CGGBP1-regulated cytosine methylation at CTCF-binding motifs resists stochasticity

BMC Genetics, 2020
Background The human CGGBP1 binds to GC-rich regions and interspersed repeats, maintains homeostasis of stochastic cytosine methylation and determines DNA-binding of CTCF.

Investigator‐Led Research to Improve the Diagnostic Assessment of Platelet Function Disorders: Reflections on the Challenges and Rewards

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Investigator‐led research and quality improvement initiatives have led to important improvements in the diagnostic assessment of platelet function disorders (PFD). Methods Personal reflections were used to summarize our contributions to knowledge on PFD diagnostic assessment, pathogenesis, and bleeding risks.

Trafficking and potentiation of Nav1.7 and Nav1.8 channels are mediated by IQGAP1

The Journal of Physiology, EarlyView.
Abstract figure legend IQGAP1 binds to the voltage‐gated Nav1.7 and Nav1.8 channels and TRPA1 channels in sensory neurons. Inflammatory mediators (IM), including PGE2 and TNFα, released during nerve injury and inflammation activate intracellular signalling messengers such as PKA, p38 MAPK and Cdc42 through their respective receptors.

DNA methylation insulates genic regions from CTCF loops near nuclear speckles

eLife
The insulator protein CTCF is essential for mediating chromatin loops and regulating gene expression. While it is established that DNA methylation hinders CTCF binding, the impacts of this methylation-sensitive CTCF binding on chromatin architecture and ...

Sex‐Modulated TACSTD2 Methylation and Hormone‐Receptor Axis Interactions in Glioblastoma: Insights Toward Mechanistic Understanding

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
Sex‐stratified analyses of the TCGA and CGGA cohorts have identified promoter‐proximal TACSTD2 CpG sites where methylation shows opposite survival associations in males and females, is independent of copy number, and correlates with TACSTD2 expression.
